Frequently asked questions

How the maths works

A student loan is a fixed-rate amortizing loan. A grace period lets interest accumulate and capitalize before payments start, so the balance you repay can exceed what you borrowed.

  1. 1During the grace period, monthly interest accrues on the balance and is capitalized (added to principal) when repayment begins.
  2. 2Base payment M = L·r / (1 − (1+r)^−n), where L is the capitalized balance, r the monthly rate and n the term in months.
  3. 3Each month, interest = balance·r and the rest of the payment reduces principal.
  4. 4An extra monthly payment goes 100% to principal, shortening the term and cutting total interest.

Figures are illustrative and exclude fees, deferment and forgiveness programs. Not financial advice.

Everything you need to know

What is interest capitalization?

During a grace period (typically six months after graduation), no payments are due but interest keeps accruing on unsubsidized loans.

When repayment starts, that accrued interest is added to your principal — you then pay interest on interest, which is why the balance can grow before you make a single payment.

Extra payments are the fastest lever

Every extra dollar you pay goes straight to principal, which cuts future interest and shortens the term — often by years.

The calculator shows exactly how many months (and how much interest) an extra monthly payment saves on your specific loan.
